Hamas has threatened "unprecedented escalation" against Israel if it does not agree soon to the Egyptian-mediated cease-fire offer, the London-based Asharq Al-Awsat reported Sunday. Hamas spokesman Ayman Taha told the paper that Egyptian Intelligence Minister Omar Suleiman was expected to arrive in Israel on Monday to convey Hamas's offer. Another spokesman for the group, Sami Abu Zuhri, said Hamas was ready to deal with one of two possibilities: Pacification or escalation. "All options are open. The ball is in the Israeli court," Abu Zuhri said, adding that if Israel continues its procrastination, aggression and blockade of Gaza, "it may lead to unprecedented escalation."
